INTRODUCTION: Ethical and economic factors have stimulated the creation and acceptance of simulators for the development of surgical skills. However, despite currently being developed and are commercially available ports for single port-surgery, little progress has been made in developing low-cost platforms and accessible for training and skills development in laboratories.

METHODS: Experimental, longitudinal, prospective and comparative study. We identified four fundamental skills in single port-surgery and four exercises were developed in a UNIPORT® simulator. 15 days of training for 1 hour daily. Evaluations were conducted in each session by an experienced surgeon, evaluating the time for doing each exercised properly and penalizing the errors previously established in each exercises. Evaluation of skill acquisition includes assessments of psychomotor area, bimanual skills, space navigation and eye-hand coordination. We analyzed the overall ratings of performance in each exercise as dimensional variables, a comparing the initial, middle and end qualification of each exercise with the Student t test, also calculated the percentage decrease in each sesion

RESULTS: The total group of subjects was 15 surgeons. Were conducted 15 training sessions. In all cases there was a reduction of the rating of each of the exercises in each session with a significant difference in all cases and the overall grade. The trend in the reduction of the rating and the percentage improvement in scores shows improvement in each session

CONCLUSION(S): This technology appears to be appropriate to ensure skills development in single port surgery through an accessible device allowing the use of multiple instruments through a single incision.
